Abstract

Procédé de mise en forme d'un tube par dilatation d'une ébauche tubulaire en polymère thermoplastique orientable, à l'intérieur d'un moule, à une température telle que la déformation de l'ébauche provoque une orientation de ses molécules de polymère. Le procédé consiste à chauffer et dilater au moins deux ébauches disposées coaxialement dans un moule 11, 12 de manière à produire un tube comportant un nombre correspondant de couches concentriques. Ces dernières peuvent être réalisées dans des matières différentes choisies pour leurs caractéristiques propres. Domaine d'application : production de tubes en matière plastique.
